In the next 5 years, lithium batteries will replace nickel-metal hydride batteries in new energy vehicles

2011 is the first year of the 12th Five-Year Plan. As an important part of the country's energy conservation and emission reduction, new energy vehicles are listed as one of the seven strategic emerging industries to accelerate the cultivation and development, and will continue to receive priority support from funds and policies. According to reports, in the 12th Five-Year Plan for the automotive industry, the development focus of new energy vehicles will be marked by the combination of vehicle electrification and hybrid power technology, with product production and industrial upgrading as the focus. The Ministry of Industry and Information Technology recently announced that my country will invest more than 100 billion yuan in the next 10 years to support the production of new energy vehicles, making my country an important producer of new energy vehicles in the world. CMIC analysts said that the important components of new energy electric vehicles are power lithium batteries, engines and energy conversion control systems. Power lithium batteries are the part with high technical barriers and concentrated profits. At present, Ni-MH power lithium batteries have just entered a mature period. This is the only battery system that has been validated, commercialized and scaled in hybrid electric vehicle battery systems. The hybrid vehicles that have been mass-produced in the world all use nickel-metal hydride power lithium battery systems. At present, Changan Jiexun, Chery A5, FAW Pentium, GM Grand Hyatt and other brand vehicles have been in demonstration operation. They use nickel-metal hydride batteries, but these batteries are mainly purchased from overseas and are still in the research and development supporting stage in application. In the field of nickel-metal hydride batteries, my country has advantages in technology and resources. Among them, nickel hydroxide has the world's leading performance, rich rare earth resources, and unique resources. In the development of new energy vehicles, the next three years will continue to be the mainstream of new energy vehicles. Then the nickel-hydrogen battery technology and the three worlds of lithium iron phosphate and hydrogen fuel power batteries will gradually be replaced by lithium ion batteries and fuel power batteries in five years. replace. Battery giants Panasonic and Sanyo also believe that lithium-ion batteries are unlikely to replace nickel metal hydride batteries within two to three years. This is important because nickel metal hydride batteries are cheap, safe, and have reached mass production. Li-ion batteries still have many problems to be solved, such as safety issues, so there is still a long way to go for commercialization. In recent years, my country's automotive lithium-ion battery industry has grown from scratch, from small to large. Although the industry started later than Japan, it has developed very rapidly. It has also invested a lot of financial and material resources in the research and development of power lithium-ion batteries. my country’s automotive lithium-ion battery research and development projects have always been a national 863 key project. Most of the materials have been localized, and they have been built in China. A large number of production lines have been introduced. The factory has many supporting materials and has formed large-scale production. Market competition is fierce, and industrial investment is important. my country's BYD, Wanxiang Group, Shenzhen bic Battery, Tianjin Lishen Battery and the United States Longyuan Joint Venture have all participated in the lithium-ion battery research. At present, BYD, the only domestic company that has mastered the large-scale production technology of lithium iron phosphate battery packs for automobiles, is in a leading position in the world. BYD’s pure electric vehicle E6 and hybrid vehicle F3DM have officially launched self-developed lithium-ion batteries. However, my country's nickel-hydrogen battery industrialization technology is not yet mature. CMIC analysts believe that domestic nickel-hydrogen battery companies should further improve the level of key materials and strive to integrate into the industrial chain. If a large amount of rare earth resources can be converted into automotive battery materials, my country still has a great opportunity. If domestic nickel-metal hydride battery companies can be integrated into the industrial chain, they will not play an important purpose, but they can serve the purpose of supplying key materials, which is also very valuable.
